Pull two x86 kernel build changes from Ingo Molnar: "The first change modifies how 'make oldconfig' works on cross-bitness situations on x86. It was felt the new behavior of preserving the bitness of the .config is more logical. This is a leftover of the merge. The second change eliminates a Perl warning. (There's another, more complete fix resulting of this warning fix, which second fix in flight to you via the kbuild tree, which will remove the timeconst.pl script altogether.)" * 'x86-build-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: timeconst.pl: Eliminate Perl warning x86: Default to ARCH=x86 to avoid overriding CONFIG_64BIT

Pull x86 bootup changes from Ingo Molnar: "Deal with bootloaders which fail to initialize unknown fields in boot_params to zero, by sanitizing boot params passed in. This unbreaks versions of kexec-utils. Other bootloaders do not appear to show sensitivity to this change, but it's a possibility for breakage nevertheless." * 'x86-boot-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, boot: Sanitize boot_params if not zeroed on creation

Pull x86/asm changes from Ingo Molnar: "The biggest change (by line count) is the unification of the XOR code and then the introduction of an additional SSE based XOR assembly method. The other bigger change is the head_32.S rework/cleanup by Borislav Petkov. Last but not least there's the usual laundry list of small but dangerous (and hopefully perfectly tested) changes to subtle low level x86 code, plus cleanups." * 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, head_32: Give the 6 label a real name x86, head_32: Remove second CPUID detection from default_entry x86: Detect CPUID support early at boot x86, head_32: Remove i386 pieces x86: Require MOVBE feature in cpuid when we use it x86: Enable ARCH_USE_BUILTIN_BSWAP x86/xor: Add alternative SSE implementation only prefetching once per 64-byte line x86/xor: Unify SSE-base xor-block routines x86: Fix a typo x86/mm: Fix the argument passed to sync_global_pgds() x86/mm: Convert update_mmu_cache() and update_mmu_cache_pmd() to functions ix86: Tighten asmlinkage_protect() constraints

Pull x86/apic changes from Ingo Molnar: "Main changes: - Multiple MSI support added to the APIC, PCI and AHCI code - acked by all relevant maintainers, by Alexander Gordeev. The advantage is that multiple AHCI ports can have multiple MSI irqs assigned, and can thus spread to multiple CPUs. [ Drivers can make use of this new facility via the pci_enable_msi_block_auto() method ] - x86 IOAPIC code from interrupt remapping cleanups from Joerg Roedel: These patches move all interrupt remapping specific checks out of the x86 core code and replaces the respective call-sites with function pointers.

Pull perf changes from Ingo Molnar: "There are lots of improvements, the biggest changes are: Main kernel side changes: - Improve uprobes performance by adding 'pre-filtering' support, by Oleg Nesterov. - Make some POWER7 events available in sysfs, equivalent to what was done on x86, from Sukadev Bhattiprolu. - tracing updates by Steve Rostedt - mostly misc fixes and smaller improvements. - Use perf/event tracing to report PCI Express advanced errors, by Tony Luck. - Enable northbridge performance counters on AMD family 15h, by Jacob Shin. - This tracing commit: tracing: Remove the extra 4 bytes of padding in events changes the ABI. All involved parties (PowerTop in particular) seem to agree that it's safe to do now with the introduction of libtraceevent, but the devil is in the details ... Main tooling side changes: - Add 'event group view', from Namyung Kim: To use it, 'perf record' should group events when recording. And then perf report parses the saved group relation from file header and prints them together if --group option is provided. You can use the 'perf evlist' command to see event group information: $ perf record -e '{ref-cycles,cycles}' noploop 1 [ perf record: Woken up 2 times to write data ] [ perf record: Captured and wrote 0.385 MB perf.data (~16807 samples) ] $ perf evlist --group {ref-cycles,cycles} With this example, default perf report will show you each event separately. You can use --group option to enable event group view: $ perf report --group ... # group: {ref-cycles,cycles} # ======== # Samples: 7K of event 'anon group { ref-cycles, cycles }' # Event count (approx.): 6876107743 # # Overhead Command Shared Object Symbol # ................ ....... ................. .......................... 99.84% 99.76% noploop noploop [.] main 0.07% 0.00% noploop ld-2.15.so [.] strcmp 0.03% 0.00% noploop [kernel.kallsyms] [k] timerqueue_del 0.03% 0.03% noploop [kernel.kallsyms] [k] sched_clock_cpu 0.02% 0.00% noploop [kernel.kallsyms] [k] account_user_time 0.01% 0.00% noploop [kernel.kallsyms] [k] __alloc_pages_nodemask 0.00% 0.00% noploop [kernel.kallsyms] [k] native_write_msr_safe 0.00% 0.11% noploop [kernel.kallsyms] [k] _raw_spin_lock 0.00% 0.06% noploop [kernel.kallsyms] [k] find_get_page 0.00% 0.02% noploop [kernel.kallsyms] [k] rcu_check_callbacks 0.00% 0.02% noploop [kernel.kallsyms] [k] __current_kernel_time As you can see the Overhead column now contains both of ref-cycles and cycles and header line shows group information also - 'anon group { ref-cycles, cycles }'. The output is sorted by period of group leader first. - Initial GTK+ annotate browser, from Namhyung Kim. - Add option for runtime switching perf data file in perf report, just press 's' and a menu with the valid files found in the current directory will be presented, from Feng Tang. - Add support to display whole group data for raw columns, from Jiri Olsa. - Add per processor socket count aggregation in perf stat, from Stephane Eranian. - Add interval printing in 'perf stat', from Stephane Eranian. - 'perf test' improvements - Add support for wildcards in tracepoint system name, from Jiri Olsa. - Add anonymous huge page recognition, from Joshua Zhu. - perf build-id cache now can show DSOs present in a perf.data file that are not in the cache, to integrate with build-id servers being put in place by organizations such as Fedora. - perf top now shares more of the evsel config/creation routines with 'record', paving the way for further integration like 'top' snapshots, etc. - perf top now supports DWARF callchains. - Fix mmap limitations on 32-bit, fix from David Miller. - 'perf bench numa mem' NUMA performance measurement suite - ... and lots of fixes, performance improvements, cleanups and other improvements I failed to list - see the shortlog and git log for details." * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (270 commits) perf/x86/amd: Enable northbridge performance counters on AMD family 15h perf/hwbp: Fix cleanup in case of kzalloc failure perf tools: Fix build with bison 2.3 and older. perf tools: Limit unwind support to x86 archs perf annotate: Make it to be able to skip unannotatable symbols perf gtk/annotate: Fail early if it can't annotate perf gtk/annotate: Show source lines with gray color perf gtk/annotate: Support multiple event annotation perf ui/gtk: Implement basic GTK2 annotation browser perf annotate: Fix warning message on a missing vmlinux perf buildid-cache: Add --update option uprobes/perf: Avoid uprobe_apply() whenever possible uprobes/perf: Teach trace_uprobe/perf code to use UPROBE_HANDLER_REMOVE uprobes/perf: Teach trace_uprobe/perf code to pre-filter uprobes/perf: Teach trace_uprobe/perf code to track the active perf_event's uprobes: Introduce uprobe_apply() perf: Introduce hw_perf_event->tp_target and ->tp_list uprobes/perf: Always increment trace_uprobe->nhit uprobes/tracing: Kill uprobe_trace_consumer, embed uprobe_consumer into trace_uprobe uprobes/tracing: Introduce is_trace_uprobe_enabled() ...

Pull irq core changes from Ingo Molnar: "The biggest changes are the IRQ-work and printk changes from Frederic Weisbecker, which prepare the code for 'full dynticks' (the ability to stop or slow down the periodic tick arbitrarily, not just in idle time as today): - Don't stop tick with irq works pending. This fix is generally useful and concerns archs that can't raise self IPIs. - Flush irq works before CPU offlining. - Introduce "lazy" irq works that can wait for the next tick to be executed, unless it's stopped. - Implement klogd wake up using irq work.

Commit c060f943 ("mm: use aligned zone start for pfn_to_bitidx calculation") fixed out calculation of the index into the pageblock bitmap when a !SPARSEMEM zome was not aligned to pageblock_nr_pages. However, the _allocation_ of that bitmap had never taken this alignment requirement into accout, so depending on the exact size and alignment of the zone, the use of that index could then access past the allocation, resulting in some very subtle memory corruption. This was reported (and bisected) by Ingo Molnar: one of his random config builds would hang with certain very specific kernel command line options. In the meantime, commit c060f943 has been marked for stable, so this fix needs to be back-ported to the stable kernels that backported the commit to use the right alignment. Bisected-and-tested-by:

Jacob Shin authored
On AMD family 15h processors, there are 4 new performance counters (in addition to 6 core performance counters) that can be used for counting northbridge events (i.e. DRAM accesses). Their bit fields are almost identical to the core performance counters. However, unlike the core performance counters, these MSRs are shared between multiple cores (that share the same northbridge). We will reuse the same code path as existing family 10h northbridge event constraints handler logic to enforce this sharing. Signed-off-by:

As reported by Klaus Schmidinger: "In VDR I use an ioctl() call with FE_READ_UNCORRECTED_BLOCKS on a device (using stb0899). After this call I check 'errno' for EOPNOTSUPP to determine whether this device supports this call. This used to work just fine, until a few months ago I noticed that my devices using stb0899 didn't display their signal quality in VDR's OSD any more. After further investigation I found that ioctl(FE_READ_UNCORRECTED_BLOCKS) no longer returns EOPNOTSUPP, but rather ENOTTY. And since I stop getting the signal quality in case any unknown errno value appears, this broke my signal quality query function." While the changes reflect what is there at: http://comments.gmane.org/gmane.linux.kernel/1235728 it does cause regression on userspace. So, revert it to stop the damage. This reverts commit 177ffe50 ("[media] dvb_frontend: return -ENOTTY for unimplement IOCTL"). Reported-by:

So, people trying I2C with the new kernel can properly reach me and find my repos." * 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: MAINTAINERS: change my email and repos

vread_hpet() uses "0xf0" as the offset of the hpet counter. To clarify the meaning of this code, it should use symbolic name, HPET_COUNTER, instead. Signed-off-by:

The trinity fuzzer triggered a task_struct reference leak via clock_nanosleep with CPU_TIMERs. do_cpu_nanosleep() calls posic_cpu_timer_create(), but misses a corresponding posix_cpu_timer_del() which leads to the task_struct reference leak. Reported-and-tested-by:

This reverts commit 9d02b43d. We are doing this b/c on 32-bit PVonHVM with older hypervisors (Xen 4.1) it ends up bothing up the start_info. This is bad b/c we use it for the time keeping, and the timekeeping code loops forever - as the version field never changes. Olaf says to revert it, so lets do that. Acked-by:

Commit cb57a2b4 ("x86-32: Export kernel_stack_pointer() for modules") added an include of the module.h header in conjunction with adding an EXPORT_SYMBOL_GPL of kernel_stack_pointer. But module.h should be avoided for simple exports, since it in turn includes the world. Swap the module.h for export.h instead. Cc: Jiri Kosina <trivial@kernel.org> Signed-off-by:

The %name-prefix "prefix" syntax is not available on bison 2.3 and older. Substitute with the -p "prefix" command-line option for compatibility with older versions of bison. This patch fixes this build error with older versions of bison.

There's DWARF unwind support only for x86 archs, so limit the unwind.o object to them only. Without this building for other archs (e.g. cross compiling for ARM) is broken. Signed-off-by:
